Subject: MIPS: math-emu: cp1emu: Fix typo when returning to register file
|
||||||
|
Origin: https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=8476cba1198d0869467d1d7bf0d5f8808a724986
|
||||||
|
|
||||||
|
The commit 08a07904e182 (MIPS: math-emu: Remove most ifdefery) in
|
||||||
|
v3.16-rc1 switched from build time to runtime detection for the CPU ISA
|
||||||
|
level.
|
||||||
|
|
||||||
|
However, along the way, a typo was introduced in the code path
|
||||||
|
to return the value to the register file. Previously, the
|
||||||
|
MIPSInst_FD macro was used but the above commit switched to
|
||||||
|
MIPSInst_RT leading to regressions.
